** This encyclopedia entry is dedicated to the life and work of Emmy Noether, a pioneering German mathematician who made groundbreaking contributions to abstract algebra and theoretical physics. ## Overview Emmy Noether (1882-1935) was a German mathematician who revolutionized the field of abstract algebra and theoretical physics with her work on symmetry and invariance. Born in Erlangen, Germany, Noether was the daughter of a mathematician and was encouraged to pursue mathematics from a young age. Despite facing numerous challenges and biases as a woman in a male-dominated field, Noether went on to become one of the most influential mathematicians of the 20th century. Noether's work had a profound impact on the development of modern physics, particularly in the areas of relativity and quantum mechanics. Her famous "Noether's Theorem" states that every continuous symmetry of a physical system corresponds to a conserved quantity, a fundamental concept that has far-reaching implications for our understanding of the universe. Noether's work also had a significant impact on the development of abstract algebra, particularly in the areas of group theory and ring theory. ## History/Background Emmy Noether was born on March 23, 1882, in Erlangen, Germany, to Max Noether, a mathematician, and Ida Amalia Kaufmann. Noether's father was a professor of mathematics at the University of Erlangen, and she was exposed to mathematics from a young age. Despite her talent and dedication, Noether faced numerous challenges as a woman in a male-dominated field. She was initially denied admission to the University of Erlangen, but was eventually accepted after a lengthy appeal. Noether's early work focused on algebra and geometry, and she was particularly influenced by the work of David Hilbert, a prominent mathematician of the time. In 1907, Noether earned her Ph.D. in mathematics from the University of Erlangen, and went on to become a lecturer at the University of Göttingen. However, due to her gender, Noether was not allowed to become a full professor, and was instead appointed as a "Privatdozent," a position that carried no salary or benefits. ## Key Information Noether's most famous contribution is her "Noether's Theorem," which states that every continuous symmetry of a physical system corresponds to a conserved quantity. This theorem has far-reaching implications for our understanding of the universe, and has been applied in a wide range of fields, including physics, chemistry, and engineering. Noether's work also had a significant impact on the development of abstract algebra, particularly in the areas of group theory and ring theory. Some of Noether's other notable contributions include: * **Noether's Theorem**: A fundamental concept in physics that states that every continuous symmetry of a physical system corresponds to a conserved quantity. * **Noether's First Theorem**: A theorem that states that every continuous symmetry of a physical system corresponds to a conserved quantity, and that the conserved quantity is a linear combination of the momenta of the system. * **Noether's Second Theorem**: A theorem that states that every continuous symmetry of a physical system corresponds to a conserved quantity, and that the conserved quantity is a quadratic combination of the momenta of the system. ## Significance Emmy Noether's work had a profound impact on the development of modern physics, particularly in the areas of relativity and quantum mechanics. Her famous "Noether's Theorem" has far-reaching implications for our understanding of the universe, and has been applied in a wide range of fields, including physics, chemistry, and engineering. Noether's work also had a significant impact on the development of abstract algebra, particularly in the areas of group theory and ring theory. Noether's legacy extends beyond her mathematical contributions. She was a trailblazer for women in mathematics and physics, and her work paved the way for future generations of female mathematicians and physicists. Despite facing numerous challenges and biases as a woman in a male-dominated field, Noether remained dedicated to her work and continued to make significant contributions to mathematics and physics until her untimely death in 1935.

Evariste Galois was a French mathematician who made significant contributions to the fields of abstract algebra and group theory, developing the concept of Galois theory, which has far-reaching implications in mathematics and physics. ## Overview Evariste Galois was a brilliant and innovative mathematician who lived a short but eventful life. Born on October 25, 1811, in Bourg-la-Reine, France, Galois was a child prodigy who demonstrated exceptional mathematical abilities from an early age. Despite his untimely death at the age of 20, Galois left behind a remarkable legacy that has shaped the course of mathematics for centuries. His work on abstract algebra and group theory laid the foundation for modern algebra, and his innovative approach to solving mathematical problems continues to inspire mathematicians and scientists today. Galois's mathematical journey began at the Lycee Louis-le-Grand in Paris, where he was admitted at the age of 12. He quickly became fascinated with mathematics and began to study advanced topics on his own, including number theory and algebra. In 1829, Galois submitted a paper to the French Academy of Sciences, which was rejected due to its perceived lack of rigor and clarity. However, this rejection did not deter Galois, and he continued to work on his ideas, eventually developing the concept of Galois theory. ## History/Background Galois's life was marked by tragedy and hardship. His father, Nicolas-Gabriel Galois, was a conservative and authoritarian figure who clashed with his son over his mathematical pursuits. In 1830, Galois was involved in a duel with a fellow student, which resulted in a serious injury that left him with a lifelong disability. Despite this setback, Galois continued to work on his mathematics, and in 1831, he submitted a second paper to the French Academy of Sciences, which was eventually accepted. Galois's work on Galois theory was a major breakthrough in the field of abstract algebra. He developed the concept of a group, which is a set of elements that satisfy certain properties, such as closure and associativity. Galois showed that groups can be used to study the symmetries of geometric objects, such as polygons and curves. His work on Galois theory has far-reaching implications in mathematics, physics, and computer science, and has been applied to a wide range of fields, including cryptography, coding theory, and quantum mechanics. ## Key Information Galois's key contributions to mathematics include: * **Galois Theory**: Galois developed the concept of Galois theory, which is a branch of abstract algebra that studies the symmetries of geometric objects. * **Group Theory**: Galois introduced the concept of a group, which is a set of elements that satisfy certain properties, such as closure and associativity. * **Symmetry**: Galois showed that groups can be used to study the symmetries of geometric objects, such as polygons and curves. * **Cryptography**: Galois's work on Galois theory has been applied to cryptography, where it is used to develop secure encryption algorithms. * **Coding Theory**: Galois's work on Galois theory has also been applied to coding theory, where it is used to develop error-correcting codes. Galois's personal life was marked by tragedy and hardship. He died on May 31, 1832, at the age of 20, due to complications from his injuries sustained in the duel. Despite his short life, Galois left behind a remarkable legacy that continues to inspire mathematicians and scientists today. ## Significance Galois's work on Galois theory has had a profound impact on mathematics and physics. His concept of a group has been applied to a wide range of fields, including cryptography, coding theory, and quantum mechanics. Galois's work has also inspired new areas of research, such as Galois cohomology and Galois representations. Galois's legacy extends beyond mathematics to the broader culture. His story has inspired countless mathematicians and scientists, including famous figures such as Henri Poincare and Albert Einstein. Galois's work has also been the subject of numerous books, articles, and documentaries, cementing his place in the pantheon of mathematical giants.
